300TE Oil In Radiator Fluid

Well, I have always been told, if there is water in your oil, then you have a head gasket problem ...............

Well, I have some oil, not a lot in my radiator fluid? The car runs well, does not overheat, does not loose oil, and does not leak coolant.

So what gives here?

A friend of mine, who is a mechanic, told me to bring it by his shop, so that he could make sure the head was correctly torqued?

Whatever you can offer, is appreaciated!
